M51 Whirlpool Galaxy

A chestnut.  Taken with a small (61mm) low-power telescope from my light-polluted back yard.  Heavily cropped, otherwise it would be too small to identify.  I’m running into the limits of my equipment — this is about 200 individual one minute exposures stacked together, taken over two nights.
